FAQs
Installation requires proper panel clearance, compatible bus bar connections, and secure mounting. Verify the 480-208Y/120 vector grouping, follow UL Listed wiring practices, and ensure adequate ventilation around the vented XFMR. Plan cable ingress/egress to minimize thermal buildup and simplify future maintenance, while respecting weight and lifting guidelines for the 430 lb unit.
K13 is a specific K-Factor rating indicating the transformer’s tolerance to harmonic currents typically produced by modern electronic loads. A higher K-Factor design helps keep voltage distortion and temperature rise within limits, improving reliability for drives, robots, and other nonlinear loads while reducing insulation wear and energy waste.
Yes. The transformer is UL Listed, signaling compliance with recognized electrical safety standards. This designation simplifies supplier qualification, reduces regulatory risk, and supports traceable quality across industrial power distribution systems, making it a robust choice for OEM panels and facility upgrades.
This 30 kVA, three-phase transformer is well-suited for factory automation, CNC and robotics systems, motor control centers, and power-distribution panels with moderate to heavy harmonic loading. Its ventilated design and 480-208Y/120 output help consolidate gearing for automation rooms while maintaining voltage stability.
Plan for the unit’s 21.13 in L, 24.88 in W, 36.88 in H footprint and 430 lb weight to ensure proper space, access, and rigging. Confirm enclosure clearances, ventilation paths, and service clearance in the electrical room. Use the provided datasheet and Eaton’s installation guidance to align with UL Listed requirements and ongoing maintenance.
